Add ceph to proxmox

 Make sure you empty the data (remove all vm's that uses this storage lvm)


Then when done, run in shell:

lvs

lvremove pve/data



Recreate some of the space

lvcreate -L 500G --thinpool data pve


then do the ceph for remaining space


lvcreate -l100%FREE -n cephosd pve


ceph auth get client.bootstrap-osd > /var/lib/ceph/bootstrap-osd/ceph.keyring

ceph-volume lvm prepare --data pve/cephosd

ceph-volume lvm activate --all


pveceph pool create ceph-vm --pg_num 128 --size 3 --min_size 2

Switching from Docker Desktop to Rancher Desktop on WSL2: Solving the Missing docker-credential-desktop.exe Error

Switching from Docker Desktop to Rancher Desktop on WSL2: Solving the Missing docker-credential-desktop.exe Error I’ve been happily running Kamal inside WSL2 on my home Windows desktop for a while. My original setup included an older Docker Desktop installation. Recently, I wanted to replicate this environment on a different machine, but I discovered that Docker Desktop had changed their licensing terms. Technically, I’m still covered by the new licensing terms, but I decided to try Rancher Desktop instead. Installing Rancher Desktop on WSL2 Installation was straightforward. I installed Rancher Desktop, configured it to integrate with WSL2, and disabled Kubernetes (since I don’t currently need it). My plan was to continue using the Docker CLI inside WSL2 alongside Rancher Desktop for container management. The Authentication Error However, when I was in WSL and tried to authenticate (for example, with Docker Hub via docker login), I ran into this error: ``` failed to store...

Proxmox Remote administration via VNC

Image
A few times I've needed to communicate via VNC, for instance when I was changing network configuration and couldn't use SSH or when I tried out Windows. Communicating with VNC to Proxmox wasn't so easy for me as it seemed in the documentation. Basically I never really got the " /etc/inetd.conf " thing to work, but this made it work from my local machine. This blog post is an alternative to the openbsd-inetd solution In the following: 2.2.2.2 is the IP of my Proxmox host 100 is the VM-ID you picked when you created the virtual machine ======================================================================== ssh -f -L 25901:127.0.0.1:5910 root@ 2.2.2.2 'nc -l -p 5910 -c "qm vncproxy 100 "'; "/Applications/TigerVNC Viewer 1.2.0.app/Contents/MacOS/TigerVNC Viewer" localhost:25901 ======================================================================== Please note that I only got TigerVNC to work, since all the other VNCs ha...
